Almost exactly 15 months to the night he won the 2014 Daytona 500 and sent his first tweet from Victory Lane at the World Center of Racing, Dale Earnhardt Jr. has crossed the 1,000,000-follower mark on Twitter.

In a sitdown interview with FOX Sports’ Michael Waltrip prior to last year’s Daytona 500, Earnhardt said he would consider joining Twitter if he won the race. Asked by a reporter in the media center during post-race interviews if it would actually happpen, he replied, "You’re paying attention. I got to get my password."

Keeping his promise, Earnhardt sent his first tweet at 2:32 a.m. ET — a selfie with the Daytona 500 Harley J. Earl trophy. Within 20 minutes, the tweet had nearly 1,800 retweets and had been favorited nearly 2,000 times.

Since that memorable night (and early morning), NASCAR’s most popular driver has sent out more than 5,700 tweets.

Now with more than 1,000,000 followers, the rest, as they say, is history.
